Hudson 'suffered from morning sickness'

Kate Hudson has allegedly suffered from terrible morning sickness.

Hudson, who recently announced that she is pregnant with her second child, felt so ill in the first months of her pregnancy that she could not keep any food down, according to Us Weekly.

"She was incredibly nauseous the first four months and told me she only gained a pound," a source said.

Hudson is pregnant with Muse frontman Matthew Bellamy's child. She already has a son named Ryder with ex-husband Chris Robinson.

Hudson can be seen next in Something Borrowed, opening in cinemas on May 6.
